“…Furthermore, the resulting SPS products exhibited improved Vickers hardness and wear rate in comparison with the analogous HP, while the other measured properties were similar. Along these lines, higher Vickers hardness [37], limited grain growth [38], higher strength [38][39], higher fracture toughness [38,40] and a more homogeneous and finer microstructures [41] were reported for SPS samples as compared to conventional HP specimens.…”

The consolidation of refractory ceramic powders at relatively milder conditions with respect to conventional methods represents an important target to achieve. Based on results recently reported in the literature, it is possible to state that the combination of the Self-propagating High-temperature Synthesis (SHS) with the Spark Plasma Sintering (SPS) technologies provides a useful contribution in this direction. Specifically, the two-steps processing route consisting in the synthesis of the ceramic powders by SHS and their subsequent densification by SPS is successfully utilized to obtain various dense MB2-based materials (M= Zr, Hf, Ta). In this regard, an important role is played by the SHS process, particularly for the synthesis of composite powders. Indeed, stronger interfaces are established among the different phases formed in-situ, so that diffusion phenomena are promoted during SPS. Additional benefits are produced by the use of the latter technology, due to the direct passage of the electric current through the powders undergoing sintering and the die containing them.

“…HP and SPS have recently been compared in the literature by different authors [5][6][7][8][9][10][11] who mainly focused their attention on the characteristics of the obtained products. Higher Vickers hardness [5,6], limited grain growth [8], higher strength [7,9], higher fracture toughness [7,10] and a more homogeneous and finer microstructure [11] of spark plasma sintered (SPSed) samples compared to the hot pressed (HPed) specimens are the main differences observed during these studies.…”

“…It should ensure that the viscosity and surface tension of the binders to meet the requirements of inkjet printing; the link compound with unsaturated functional group content, should be able to ensure the ink in the UV-curable irradiation. Two or more functionality have been taken to the substrate with the use of the curing effect of high-quality film [3]. The preparation of dye-based inkjet UV inks binders experiments choice three different functional acrylate as raw materials; meet the requirements of the ink, the viscosity and curing properties at the same time to ensure that the dye is fully dissolved.…”

With the development of ink-jet technology and digital proofing, the application of UV-curable ink for inkjet printing has increasingly been concerned. The characteristics of UV-curable ink, such as fast-curing, non-blocking of nozzles, no evaporation of solvent make it possess obvious development predominance in the field of inkjet printing. The purpose of this study is to obtain a formula of dye-based UV-curable ink used indoors through tests, thus it will promote the application of UV-curable ink in the digital inkjet field. Based on the characteristics of indoor inkjet printing, we confirmed the category of raw materials in formula of dye-based UV-curable ink, such as base materials of vehicles, dye and photoinitiator. In the vehicle formula experiments, by using three types of optically active monomer with even experimental design, viscosity and surface tension as the indicators, we obtained the three types of vehicle optimum ratio suitable for the requirements of inkjet printing. In the formula experiments, ultraviolet light transmittance of dyes was tested firstly. With the ultraviolet absorption characteristics of photoinitiator, we confirmed the matching design of dye and photoinitiator. Based on the indicators of curing rate and color density, we obtained the optimum formula of the CMYK four-color UV rays curing ink by orthogonal experimental methods.
